Backflush RO Unit?

Hey guys,

MY RO/DI unit does not have a backflush valve on it. I was wondering what the easiest way to do this would be without the valve. I have never performed a backflush on the membrane and I have noticed that the rate of water made by the unit each day has begun to drop substantially.

take the flow restrcitor out of the waste water line and let it run for about 20 seconds.

Never thought of that. Thanks. Also can you run water backwards (put water in your drainage side) Will that mess anything up?

Water shouldn't go through that way...there should be a check valve in the waste line. The easy way to do this is to put a tee fitting and a valve in the waste line ahead of the flow restrictor. Then you can just open the valve to backflush.
